LUBRICATOR.

Application filed February 24, 1908. Serial N 0. 417,418.

Specification of Letters Patent.

Patented Sept. 15, 1908.

To all whom it may concern:

Be it known that I, JAMES WILLIAM DOMVILLE, a subject of the King ofGreat Britain, residing at 29 Wellington street, in the city ofMontreal, in the district of Montreal, in the Province of Quebec, in theDominion of Canada, have invented certain new and useful Improvements inLubricators, of which the following is a specification.

The invention relates to improvements in lubricators, as described inthe present specification and illustrated by the accompanying drawingsthat form part of the same.

The invention consists essentially of a particular bag or package formedof textile material and adapted to permit the flow of grease steadilyand evenly therethrough on the application of friction.

The objects of the invention are to economize in the consumption oflubricant and to bearing free from foreign matters.

In the drawings, Figure l is a perspective view of an open bearingshowing the bag of lubricant in position resting on the journal. Fig. 2is an enlarged perspective view of the bag with a corner of the flapfolded back to disclose the grease therein. Fig. 3 is an enlargedsectional view showing the web of the material and the filler with whichit is saturated.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is an open bearing and 2 the shaft turningin said bearin 3 is a bag or package of any suitable shape according tothe journal box or bearing in which it is to be applied and preferablyformed of canvas, though any other textile or like material may be used.

4 is a flap, covering the open slit 5 longitudinally arranged in the topof the bag, the said flap 4 is shown as closed by the fasteners 6 of thedome type. It will be readily understood that any suitable form ofopening may be made in this bag for the introduction of the grease 7 andfurther that it may be fastened in any desirable manner either by sewingor other styles of fastening devices easily opened, or again the bag maybe completely closed with the grease therein contained having no slitfor the ingress of said grease, other than what might be originally asewed up end or side.

8 is a filler with which the bag or package 3 is saturated and fillingin the interstices between the threads of the web of the textilematerial and also soaking said threads. The filler 8 is composed of amixture of animal and mineral oil in proportions varying according toclimatic conditions, particularly referring to heat and cold. The saidfiller in cool weather congeals and fills up the interstices of the webof the material.

The quantity of mineral oil is much reduced-in warm weather and theproportion of animal oil much increased, as the tendency is for the oilto thin out with the heat and by adding a greater proportion of theanimal oil, the mixture is denser and not quite so liable to run freelythereby still keeping the bag well soaked and the interstices of the webfilled.

The shape of the bag or package 2 as before mentioned is notnecessarily'essential to the proper operation of the invention for wherethe bag is introduced into journal boxes, such as railway car journalboxes, it will be necessary to modify the shape thereof from that usedin an open bearing, therefore, for each type of bearing a particularshape of bag will be made. The filler 8 or solution in which the saidbagis saturated is, however, an extremely salient feature in the operationof the device, for in the rotation of the shaft 2, the heat will meltthe filler which has congealed subsequent to saturation, and make itflow on to the journal together with the grease to which it has uniteditself in the warming up of the bearing, thus acting as a direct agentin starting the flow of the grease through the textile material andobviating any difficulty incident to the burning or scorching of thesaid textile material from the rotation of the shaft previous to thefree flow of the melted grease therethrough.

Vhat I claim as my invention is:

In a lubricant, a bag or package of cloth material containing grease ina comparatively solid mass and a compound of matter Signed at the cityof Montreal, in the composed of animal and mineral oil in pro- Provinceof Quebec, in the Dominion of portions varying according to Weather con-Canada, this 14th day of February, 1908.
